ALONZO HANMER AND DAVID GRIM, OF PITTSBURG, PENNSYLVANIA; SAID ALONZO HANMER ASSIGNS HIS RIGHT TO PHILIP L. GRIM, OE BEAVER OOU'NIY,A PENN SYLVANIA Leners Patent No. 1oo,03o,.dad February 22, 1870.

Men- IMPRovED RAILWAY-RAIL The Schedule refen'ed.to in these Letters Patent and making part o! the same ,To all whom fit/may concern Be it known that we, ALONZO HNMER and DsviD GMM, both ofthe city of Pittsburg, in the county of Allegheny, and State of Pennsylvania, have invente-l a new and .useful Improvement in Railroad- Rails, of which the follo\\'ing,tnken in connection with the accompanying drawings, is a specification.

Nature and Objects of the Invention.

-Our invention relatesto an improvement in that class of rain'oad-rails that are made in two parts, one

part constituting the flange and web, and the other the crown' or head. t

The invention we have made consists in so constructing each pant, as that, when placed properly'ztogether, they will support one another, the object being to hold a detachable crown or head firmly in' place without vthe use oi' bolts, rivets, or wedges, and yet permit suiii- In forming our nuprmed rail, we make the flange T ot' the us'uul shape, but divide the web A longtudinally, so as to form a deep V- shaped groove, O, the upperledges of which are turned inward by properly- .constructed rolls, to produce a slight bead or,rib,e, at

each of those points.

The top or crown B, which may be of steel or iron,

is rolled separately, and with a tongue, D, on'its lo'werside, corresponding in shape with that of the groove C in the web.

On' each side of this tongue D, and immediately beueath the crown, is a shallow channel, j; in which the ribs e e are intended to lit.

The crown B is also large enough toallow its sides or cheeks s to overhang .and clasp the edges of the web.

'lhe parts being so constructed, the' tongueD of the crown B is forced down into the groove C, the sides of which spring apart just sutlicient to allow the ribs e e to enter the channels f f in its sides, when they close up and hold the tongue with a -vise-like grip, while the vover-hanging cheeks s s of the crown clasp the top of the web A, binding the parts so firmly together that very considerable force is requiredto separate them.

' C' laim.

We claim the channels ff in` the tongue D, in combination with the ribs e e in the groove G, as a means of uniting the head or crown ofa two-part rail to thel I web or base without the use of bolts, rivets, or wedges, as shown and set forth.

In witness whereof, we have-hereunto set our hands in the presence of two subscribing witnesses.'

ALONZO HANMER.

DAVID GRIM.
